I use Dropbox Business Standard and am the admin. I have 4 root level folders that I see if I open the Dropbox folder on my computer or at dropbox.com. I want to add a fifth. Can I? On Dropbox.com, the +Create button is greyed out. In Finder in my Dropbox folder on my computer, if I click on File in the menu bar, New Folder is greyed out. If I create a new folder on my desktop and try to drag it into my Dropbox root folder, it bounces back. If I'm already inside one of my Dropbox subfolders, I have no trouble creating new folders there. What is going on?
